HORIZONTAL LIGHT.

Specification of Letters Patent.

Patented June 11, 1907.

Application filed November 5, 1906. Serial No. 342,111.

To aZZ whom it may concern.-

Be it known that I, ADOLPH G. KAUFMAN,

, a citizen of the United States, residing at New York, in the countyand State of New York, have invented a new and useful Horizontal Light,of which the following is a specification.

This invention relates to incandescent gas burners, and has for itsobject to provide a burner of this character in which the mantle will beheld in a horizontal, or inclined, plane, so that it will have theadvantages of the drop, or inverted light including throwing the lightdirectly down without the shadow of the burner being interposed, andwill have certain advantages over the inverted light to be hereinafterpointed out. Further objects of my invention being, first, to providemeans to hold the mantle in a horizontal, or inclined position in asecure and firm manner; second, to provide means to distribute the gasflame in an even manner over the mantle; third, to provide means for theeasy regulation of the flow of gas; fourth, to provide a suitable globe;and, fifth, to provide an improved globe holder and flame and heatshield.

My invention is illustrated in the accompanying drawing, in which-Figure 1, is a side elevation of a horizontal light constructedaccording to my invention, the globe being in section; Fig. 2, is a planview of the mantle holder; Fig. 3, is a view of a modified. form of myinvention; Fig. 4, is a bottom plan view of a modified form of thedischarge nozzle, with the inclosing mantle Fig. 5, is a side elevationthereof; Fig. 6, is a side elevation of another modified form; Fig. 7,is a plan view of the gas regulator; and, Fig. 8, is a vertical sectionthereof.

In the accompanying drawing the several parts of my invention areindicated by numerals of reference; and in practice I provide a light inwhich, as shown in Fig. l, the mantle 9, is held in a horizontalposition, the gas discharge nozzle 10, being also in a horizontalposition. The discharge nozzle 10, is larger than the column, or pillar11 as clearly shown in the drawing, and is provided with a plurality ofperforations 12, part of which are on the under side, as shown, so thatwhen the gas and air is discharged into the mantle the flame will bedistributed in an even manner over the entire surface thereof, andwithout waste of gas, as usually occurs where the mantle is inverted,for the reason that no gas escapes from the mantle without performingits function, and less pressure is required to force the flame againstevery part of the mantle.

The mantle 9 is mounted on the usual supporting ring 13, having feet141; but in order to hold the mantle firmly in position, I provide theholding spider 15, with a plurality of humps 16, corresponding in numberto the legs 14, of the ring 13, and proportioned in height so that whenthe angular portions of the legs 14 are in engagement with the humps, asshown in the drawing, the ring 13 will be drawn firmly against thespokes 17, of the spider, thereby holding the mantle 9 firmly 1nposition.

Instead of holding the mantle in a horizontal position, as shown in Fig.1, it may be held in an inclined position, as, for instance, in themanner shown in Fig. 3 the pillar 11, being curved so that the mantle isheld in an inclined, downwardly directed position; but it is evidentthat the inclination might be reversed, or made at a difl'erent anglewithout preventing the downward radiation of light, and withoutpermitting the escape .of flame from the base of the mantle, the mantlebeing in substantially a horizontal position.

While the gas flame will be evenly distributed by the form of nozzleshown in Fig. 1, I may provide a different form of nozzle, as shown inFigs. 4, and 5, in which the perforations 12 are all on the sides andbottom. As the gas flame will naturally flow upward, by forcing itagainst the sides and bottom of the mantle, the entire mantle will bereachedby the flame, as will be readily understood. Instead of using theform of nozzle shown in Figs. 4, and 5, I may use the form shown at 10,in Fig. 6, by which the flame will be driven downwardly and outwardly.

To provide for the easy regulation of the flow of gas, I have providedthe improved gas regulator shown in Figs. 7, and S. This regulatorconsists of a .nipple 18, having a thimble-shaped extension 19, which isslotted transversely at right angles, the slots 20, extending to thebase of the extension, as shown in Fig. 8, and the slots are made ofsufficient width to allow of the [low of considerable gas through thcm.The nipple is also provided with a casing 21, which is pro vidcd with ascrew-tlneaded portion 22, which may be screwed into the air mixer 23. Ialso provide a sleeve 24, which is screwed upon the nipple 18 and has areduced extension 25, with an opening 26, in the end thereof; and theextension 25 is so shaped internally that when the sleeve 24 is screwedtightly upon the nipple 18, the four sections of the thimble-shapedextension 19, will be drawn into contact with each other at the edges,as indicated in dotted lines in Fig. 7, and by providing a gasket 27, toprevent the escape of the gas from the bottom of the slots 20, the flowof the gas will be entirely cut off and the regulation is such that apartial turn backward will open the slots to their full extent; so thatby mounting a handle 28, in the sleeve 24, and providing the casing 21,with a slot 29, the flow of gas can be shut oil by bringing the handleinto the position shown in dotted lines in Fig. 7, while intermediate ofthese points the flow of gas will be regulated as desired, as will bereadily understood.

WVith this form of light, a globe of special construction is necessary,and accordingly I have provided a globe 30, which may be secured to theglobe holder 31, by screws 32; and has an open top 33, an opening in theside of the bottom thereof 34, and a slot 35, extending from the opening33, to the holder 31, the slot being of suflicient width to allow thepassage of any flame which might escape from the base of the mantlethrough improper adjustment, and also to prevent the uneven heating ofthe globe by the heat accending from the base of the mantle.- Theopening 34 being at one side of the bottom, will allow the admission ofair, but is sufficiently far from the center to prevent the falling ofany debris from the mantle to the floor, especially while hot.

The globe holder 31, comprises the annular flange 36, forming the seatfor the globe, a

shield 37, ending in a ring 39, which fits upon the air mixer 23; andintervening between the globe seat 36, and the shield 37, is an annularportion 38, having a plurality of air holes 40. By this constructionshould the pressure be great enough to drive the flame out at the baseof the mantle, the shield 37 will prevent the flame reaching the airmixer 23, and igniting the gas therein, and this shield will alsoprevent the overheating of this air mixer. Should the flame strike theshield, the air holes being in the annular part 38, the flame will bedirected outwardly away from the air mixer, thus avoiding all danger ofignition of the gas in the mixer. It will thus be seenthat this part notonly serves to hold the globe in position; but is quite an essentialfeature for this form of light.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is
